Hass avocado

Persea americana 'Hass'
Cultivar 'Hass'
Origin First grown at La Habra Heights, California in 1926 from the seed of an unknown or undetermined subspecies of Persea americana, patented 1935 in the US

The Hass avocado , sometimes marketed as the Haas avocado , is a [2][3]

The Hass avocado is a large-sized fruit[4] weighing 200-300 grams. When ripe the skin becomes a dark purplish-black and yields to gentle pressure.[5] When ready to serve, it becomes white-green in the middle part of the inner fruit.

Owing to its taste, size, shelf-life, high growing yield and in some areas, year-round harvesting, the Hass cultivar is the most commercially popular avocado worldwide. In the [2][5]

History

A young Hass avocado sprout

All commercial, fruit-bearing Hass avocado trees have been grown from grafted seedlings propagated from a single tree which was grown from a seed bought by Rudolph Hass in 1926 from A. R. Rideout of [2]

In 1926, at his 1.5-[2] The Hass avocado had one of its first commercial successes at the Model Grocery Store on Colorado Street in Pasadena, California, where chefs working for some of the town's wealthy residents bought the new cultivar's big, nutty-tasting fruit for $1 each, a very high price at the time (more than US$15.00 of inflation adjusted value by 2007).

Hass [2] However, Hass made a profit of less than US$5,000 through the patent because cuttings from single trees sold by Brokaw were then propagated to graft whole orchards.[1]

Rudolph Hass carried on as a postman throughout his life and died of a [2]

By the early 21st century the US avocado industry took in over $1 billion a year from the heavy-bearing, high quality Hass cultivar, which accounted for around 80% of all avocados grown worldwide.[2]

Fate of mother tree

Owing to later suburban sprawl in Southern California, the mother tree stood for many years in front of a residence in La Habra Heights. The tree died when it was 76 years old and was cut down on 11 September 2002 after a ten-year fight with [2] Each year in mid-May the city of La Habra Heights celebrates the Hass avocado at its Annual La Habra Heights Avocado Festival.

Bearing pattern

Hass avocado trees, like some other cultivars, may only bear well every other year. After a year with low yield, often because of cold, for which the tree does not have much tolerance, yields may be very high the next year. However, the heavy crop can deplete stored carbohydrates, lowering the following season's yield and this can set the tree into a lifelong alternate bearing pattern. Southern California Hass Avocado groves have good soil and drainage, plentiful sunlight and cool gentle winds from the oceans which help the fruit grow. These conditions hold throughout the year, so there are always fresh harvests of Hass avocados in Southern California.[8]

Nutritional Value

Like all avocados, Hass avocados are high in healthy fats, vitamins C, E and B, potassium, and folic acid.
